“…Studies have used various metamaterial structures as a reflector to overcome these shortcomings [12]- [24]. In [12]- [14], vialess rectangular high-impedance surface (HIS) cells are homogeneously placed under the outer edge of the antenna to realize artificial magnetic conductor (AMC) characteristics, thereby realizing a unidirectional pattern even in a low-profile structure. However, improving radiation performance is insufficient due to the narrow bandwidth of the AMC characteristics.…”

A novel method of enhancing radiation performance is demonstrated by applying a hybrid reflector composed of inhomogeneous metamaterial elements to a four-arm log-periodic toothed antenna. The operation of the antennas by various metamaterial cells is observed, and the causes of the radiation performance deterioration and narrow bandwidth are investigated through the field distribution analysis. The metamaterial cells are arranged in suitable positions under the antenna for good radiation performance and wide bandwidth according to AMC and EBG characteristics. In the proposed hybrid reflector, surface wave suppression characteristics are used for impedance stabilization by placing the I-shaped EBG cell under the inactive region of the antenna. The performance of the fabricated antenna with dual linear polarization capability is verified by measuring co-and cross-polarization radiation patterns. The newly proposed hybrid reflector for the four-arm log-periodic toothed antenna represents an over 4 dBi realized gain within an impedance ratio bandwidth of over 11.6:1.INDEX TERMS Four-arm LP-toothed antenna, electronic support measures, wide gain bandwidth, metamaterial, high impedance surface, artificial magnetic conductor, electromagnetic bandgap.

“…Compared with the sub-6 GHz band, the spectrum resources at millimetre-wave (mm-wave) bands are more abundant, which drives the research and development of low-cost wideband mmwave antennas [1,2]. Due to the effectiveness in mitigating multipath interference and fading, the circularly polarised (CP) antennas have aroused great interest in wireless communication systems [3,4]. For these reasons, wideband mm-wave CP antennas attract increasing interests in recent years.…”

A circularly polarised (CP) antenna with highly symmetrical radiation patterns and wide operating bandwidth is presented for millimetre-wave (mm-wave) applications. By loading four parasitic inverted-F components around a SIW-fed S-dipole antenna, better axial ratio (AR) performance and higher gain performance are realised. Furthermore, the proposed antenna can achieve highly symmetrical radiation patterns in different elevation planes within a wide operating band. This unique feature makes it advantageous to more uniform signal coverage. To verify the effectiveness of the antenna, a prototype is fabricated and measured. The experimental results validate that the antenna covers the impedance bandwidth of 49.1% (21.2-35 GHz) and the AR bandwidth of 51.3% (20-33.8 GHz). Besides, the antenna peak gain can reach 10.42 dBic at 28.5 GHz. More importantly, the antenna can radiate extremely symmetrical and uniform waves in different elevation planes within a wide operating band (21-29 GHz). Attributed to these merits, the presented antenna shows great potential in various mm-wave systems.
